Description

I am trying to detect DNS Tunneling.
For this I use the DNS logger in Suricata 2.0.
But when TXT answers have lot of data, the DNS logger say '<no data>'.

Sorry is not the parser but the DNS logger.

I think this is only matter of extending the dns loggers. If it turns out to be more involved it will likely go into 2.1.

I'm not getting any 'no data' with this branch, are you sure you tested the branch from pull request 967?

Sorry, i made a mistake with my suricata.

It's logging correctly the answers now.

Thank you for your help. You can close the ticket. :)
